Like Angus, SA or DA doesn't seem to bother me much either. What counts is when I pull the trigger, it goes bang. I've gotten so used to my PCR, that when I shoot my Colt 1991A1 on the range, or any other gun with a safety, I forget to disengage it. So I go click, it does nothing. I'd rather not have that happen in a combat situation.
Just my $0.02.
